They're going to fire up the desal plant that's been sitting disused for the last twenty years where I live. I think they're discussing double the current water rate for desal water. There are 12-18 month waits for getting wells drilled in the Central Valley right now, with some communities having water trucked in.
One thing I'm surprised about, what with all the subsidies given for particular crops at the Federal and State level already, is that they haven't talked about "paying not to plant", which they were doing 30 years ago simply to keep the price of certain crops up. With over a billion dollars in emergency money dedicated to drought mitigation and awareness, they could probably take a hundred million or so of the "awareness" money, and instead of using it for TV commercials telling people not to wash their cars, apply it to leaving fields fallow, which would save exponentially more water than a carwash ban.
Of course as I have complained elsewhere on the forum, no discussion of ending the Delta smelt water diversion, or any of the other enviro diversions that are basically dumping billions of gallons of fresh water into the ocean. Some portion of the ag water at least, seeps back down to replenish the aquifers. The diverted water is just gone.
